Description

A screw driven extruding and kneading multi-function washing machine core

technical field

The invention relates to the field of washing machines, in particular to the core functional part of the washing machine—the core of the washing machine, which can improve the cleaning quality of the washing machine, save energy (water, electricity), and avoid the damage of residual chemical detergents in the clothes to human skin .

Background technique

At present, domestic washing machines generally have defects such as unsatisfactory cleanliness or easy damage to clothes during washing, and waste of water, time, and electricity. The market calls for the development of a washing machine that is higher in cleanliness than the existing drum washing machine but not like a wave-wheel washing machine. Such a new type of multi-functional fully automatic washing machine that is easy to damage clothes, the problem is the core functional part of the washing machine-the washing machine core.

The first practical washing machine that appeared on the market was the pulsator washing machine. As the name suggests, the pulsator washing machine uses the pulsator to drive the water contained in the washing container (inner bucket) to do a rapid tumbling and swirling motion. Different, so there is a big difference between the moving speed of water and the moving speed of clothes, so that soft rubbing occurs between water and clothes, and soft rubbing occurs between clothes due to the difference in moving speed. Kneading produces a cleaning effect on the clothes, coupled with the chemical action of the detergent and the stains, thereby removing the stains attached to the clothes, achieving a function similar to manual wringing of clothes to remove stains.

However, the pulsator of this type of washing machine is located at the bottom of the inner tub and rotates at a relatively high speed. Due to the gravitational force of the earth, the clothes will inevitably fall downward and cause rigid friction with the high-speed rotating pulsator, which may easily cause damage to the clothes. Moreover, the water vortex generated by the high-speed rotating pulsator is likely to cause the entanglement between the clothes, thereby affecting the cleanliness of the parts of the clothes.

In order to reduce the damage and entanglement of clothes, people invented the drum type washing machine according to the basic principle that washing machine washing is to use water flow and soft rubbing between clothes and clothes to remove stains. The drum type washing machine drives the water contained in the drum (washing container) to do a rapid tumbling and swirling motion through the high-speed rotation of the drum, and lifts the clothes to a certain height through the lifting ribs evenly distributed on the drum circumference and then throws them away. Into the water, make soft rubbing between water and clothes, clothes and clothes, and the collision and rubbing between clothes and water, coupled with the chemical action of detergent and stains, so as to remove the stains attached to the clothes, and tumbling swirl The water has the effect of accelerating dissolution and evenly distributing detergent.

However, the size of the drum of the drum type washing machine is generally much larger than that of the pulsator, and it is also a washing container. If the rotation speed is too fast, it is easy to cause centrifugal force on the clothes, and the tumbling swirl of the water of the drum type washing machine is faster than that of the pulsator type washing machine. The turbulence and swirl of water should be moderate, and the amount of water should be less, so the action time of water on clothes should be short, and the effect of soft rubbing between clothes and water, clothes and clothes cannot be achieved, so the washing effect is average It is worse than the top wheel washing machine, but the damage to the clothes is less when washing, and it is less entangled.

It should be pointed out that no matter how different the above two washing methods are, there is one disadvantage that is the same, that is to remove the residual stain mixture that penetrates into the clothes fibers and its chemical corrosion damage to clothes and human skin. They are all methods of throwing out the stain mixture only by high-speed centrifugal force (only equivalent to manual wringing), and it can only be done after the washing process is completed and the water is drained, not during the washing process. Therefore, the decontamination effect of washing is weak, and the number of times to remove the stain mixture penetrating into the clothes is generally only three to four times. Clean clothes and remove damage to clothes and human skin.

Contents of the invention

In view of the existing washing machine which only uses high-speed centrifugal force to throw out the stain mixture (equivalent to manual wringing), it is impossible to remove the residual stain mixture infiltrated in the clothes fibers to the greatest extent, so it is impossible to clean the clothes to the greatest extent, and To eliminate the defects of damage and entanglement to clothing and human skin, the present invention aims to provide a screw-driven extruding and kneading multi-function washing machine core, by adding an axially movable movable plate and a relative to the drum of the washing machine. The rotatable rotary fixed plate of the drum of the washing machine not only retains the washing function of the traditional washing machine core, but also performs the multi-functional functions of squeezing, kneading and rubbing the washed clothes, thereby improving the washing quality and Washing efficiency; and reduce the number of washings to achieve the purpose of reducing damage to clothes, saving water and electricity, and reducing damage to human skin caused by detergent residue chemicals.

In order to achieve the above object, the technical solution adopted in the present invention is: a screw-driven squeeze-kneading multi-function washing machine core, including a rotatable drum, and its structural feature is that the B end of the inner chamber of the drum is provided with A rotating fixed plate, which cannot move axially during washing operations in the direction of the drum axis, can be driven by the drum to rotate around the drum axis; It is a moving plate that moves back and forth linearly in the axial direction, and the moving plate and the rotating fixed plate form a squeezing and rubbing mechanism for extruding and rubbing the laundry to enhance the washing effect.

The composition of the extruding and kneading mechanism is that a differential screw driving device is provided on the non-washing working side of the moving plate to drive the moving plate to move axially reciprocating and linearly along the axis of the drum, and the differential screw driving device It consists of a screw connected to the non-washing side of the moving plate at one end, a screw sleeve screwed on the screw rod with the same thread parameters as the screw rod, screwed on the screw sleeve with the same thread parameters as the outer thread of the screw sleeve and rotates relative to the axis of the drum Instead of a screw shaft that can move axially. An anti-rotation fork is arranged between the screw sleeve and the screw sleeve shaft to limit the rotation of the screw sleeve relative to the screw sleeve shaft, and an anti-rotation rod is arranged between the screw rod and the screw sleeve shaft to limit the rotation of the screw rod relative to the screw sleeve shaft.

The washing surfaces of the rotating fixed plate and the moving plate are provided with protruding pulsator ribs, which can make the water form a tumbling swirl and increase the speed of the tumbling vortex.

The circumferential wall of the drum, the end face of the drum A, and the moving plate are all provided with small water-permeable holes for water intake and drainage.

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, the core of the screw-driven squeeze-kneading multi-function washing machine adds a moving plate 1 that can move axially around the axis of the drum 6 in the drum 6 of the existing drum washing machine. A rotating fixed plate 2 that can rotate around the axis but cannot move axially with the same axis, and a fixed plate 2 installed on the non-washing side of the moving plate 1 that can drive the moving plate 1 to move in a straight line along the axis of the drum 6. differential screw drive. The moving disc 1 is driven to make an axial reciprocating linear motion along the axis through a differential screw driving device. When the moving plate 1 moves axially and linearly to a closer distance from the rotating fixed plate 2, the closer distance refers to the distance between the moving plate 1 and the rotating fixed plate 2 that can squeeze and knead the clothes, and the moving plate 1 will be in contact with the rotating fixed plate. The discs 2 work together to clean the clothes in an all-round way of squeezing, kneading and rubbing. And this moment, the rubbing and the collision rubbing and chemical decontamination of the clothing and water between the aforementioned water and clothes, clothing and clothing due to speed differences also exist, and due to the increase between the moving 1 plate and the rotating fixed plate 2 The functions of squeezing, kneading and rubbing the clothes due to joint clamping enhance the function of washing and decontamination.

As shown in Figure 3, when the moving plate 1 moves axially to close to the rotating fixed plate 2 and squeezes, kneads, and rubs the clothes to complete a round of washing work due to common clamping, the screw sleeve shaft 3 in the differential screw drive device starts to reverse. Under the action of the screw shaft 3, the screw sleeve 4 and the screw rod 5 are retracted along the axis in the opposite direction. After the moving plate 1 and the rotating fixed plate 2 repeatedly squeeze, knead, and rub dozens of times, the residual stain mixture infiltrated in the fibers of the clothes will be removed to the greatest extent, which is equivalent to repeated stepping on the clothes with the feet or repeatedly beating the clothes with a mallet. The washing effect is much cleaner than the residual stain mixture permeated in the fibers of the clothes that is simply thrown out by centrifugal force (only equivalent to wringing out the clothes) in the existing washing machine, and the washing quality of the clothes is also much better; is removed to the greatest extent, so the chemical damage to the clothes is much lower, especially during the rinse cycle. Thereby also avoiding the damage of the residual chemical detergent in the clothes to human skin.

Working process of the present invention: Fig. 1 and Fig. 3 respectively represent the position (initial position) of mobile dish 1 when non-washing work and the limit position (end position) of mobile dish 1 when washing work. As shown in Figure 3, the screw sleeve shaft 3 can rotate around the drum axis but cannot move axially. It can perform forward and reverse rotation movements under the drive of power. Under the action of the internal thread of the rotating screw sleeve shaft 3, Drive the external thread movement of the screw sleeve 4 with the same thread parameters as the internal thread of the screw sleeve shaft 3, and then drive the screw sleeve 4 to do axial reciprocating linear motion; The external thread movement of the screw 5 with the same thread parameters, and then drives the screw 5 to perform axial reciprocating linear motion, so as to achieve the purpose of pushing and pulling the movable disk 1 to perform axial reciprocating linear motion.

As shown in Figures 1 and 3, the rotary fixed plate 2 can rotate around the axis of the drum 6 under the drive of the drum 6 during washing work but cannot move axially, so the distance between the movable plate 1 and the rotary fixed plate 2 is The laundry creates a clamping force. In addition to being constantly rubbed and washed by the soft friction between water and clothes, clothes and clothes, and the collision and rubbing of clothes and water, the clothes that are constantly tumbling with the water flow in the drum are rotated on the moving plate 1 along the axis. When the disk 2 moves axially and linearly, the clamping force generated by the clothes between the moving disk 1 and the rotating fixed disk 2 and the rotational inertia force of the moving disk 1 and the rotating fixed disk 2 make the clothes fully squeezed, The washing effect of kneading and rubbing greatly strengthens the washing and decontamination effect on clothes, but it does not damage clothes. It is more effective for removing the residual stain mixture penetrating in clothes fibers.

Compared with the existing drum-type or pulsator-type washing machine, the beneficial effect of the present invention is: on the premise of retaining the function of the existing drum-type or pulsator-type washing machine, through the relative movement of the moving plate and the rotating fixed plate and The pulsator ribs protruding from the working surface of the moving plate and the rotating fixed plate have the effect of rubbing, kneading and squeezing the clothes in all directions during the washing process, which greatly strengthens and improves the washing and decontamination effect on the clothes But it does not damage the clothes, thereby improving the cleaning quality of the washing machine, thereby saving energy (water, electricity), and avoiding the damage of the residual chemical detergent in the clothes to human skin. It has high cleaning performance, good washing effect, energy saving (water, electricity) and environmental protection.

A screw-driven extrusion-kneading multi-function washing machine machine core, as shown in Figure 1 and Figure 3, includes a rotatable horizontal drum 6, and the B end of the inner cavity of the drum 6 is provided with a rotating fixed plate 2, The rotary fixed plate 2 that cannot move axially during the washing operation in the axial direction of the drum 6 can be driven by the drum 6 to rotate around the axis of the drum 6; The moving disk 1 is a moving disk 1 whose axis moves back and forth linearly in an axial direction. The moving disk 1 and the rotating fixed disk 2 form a squeezing and rubbing mechanism for extruding and rubbing the laundry to enhance the washing effect.

The composition of the extruding and kneading mechanism is that a differential screw drive device is provided on the non-washing working side of the moving plate 1 to drive the moving plate 1 to move axially reciprocating and linearly along the axial direction of the drum 6, and the differential speed The screw driving device includes a screw 5 connected to the non-washing side of the moving plate 1 at one end, and is screwed on the screw 5 with a screw sleeve 4 having the same thread parameters as the screw 5. The screw sleeve shaft 3 with the same thread parameters and which rotates relative to the axis of the drum 6 but cannot move axially. Between the screw sleeve 4 and the screw sleeve shaft 3, an anti-rotation fork 8 that restricts the rotation of the screw sleeve 4 relative to the screw sleeve shaft 3 is provided, and between the screw rod 5 and the screw sleeve shaft 3, a limit screw rod 5 is arranged to rotate relative to the screw sleeve shaft. 3 rotate the anti-rotation lever 9.

As shown in Figures 2 and 4, the washing surfaces of the rotating fixed plate 2 and the moving plate 1 are provided with protruding pulsator ribs 7, through which the pulsator ribs 7 can make the water form a churning swirl And enhance the movement speed of the tumbling swirl.
